WATER-HEATER FOR LOCOMOTlVE-BOILERS.

SPECIFICATION forming part of Letters Patent No. 616,541, dated December 27, 1898. Application filed November 26, 1897. Serial No. 659,791. (No model.)

To aZZ whom it may concern:

Be it known that 1, PETER ALSDROFF Kin- BURG, a citizen of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented a new and useful Improvement in Feedater Heaters for Locomotive-Boilers, of which the following is a specification.

The object of my invention is to produce a heater for the feed-water that will utilize the heat from the exhaust and also the heat from the furnace gases after they have passed through the lines.

Reference will be had to the accompanying drawings, in which- Figure l is a front end view of thesmokebox of a locomotive. Fig. 2 is a side view. Fig. 3 is a vertical sectional view through the heater on line 3 3, Fig. 4. Fig. 4 is a bottom plan view of the heater. Fig. 5 is a top plan sectional view through the heater on line 5 5 of Fig. 3. Fig. 6 is a modified form showing arrangement with valves for changing course of feed-water. Fig. 7 is a plan detail showing delivery-pipe entering the front flue-sheet.

In place of the ordinary exhaust-nozzle I place a nozzle A, which is constructed with the water-space B encircling the nozzle. This space E is divided vertically by the partitionwalls 0, one of which, D, extends from top to bottom, thereby shutting 0d the space 13 entirely, while all the other partition-walls have an opening at the top and bottom alternately. (See opening E at top and F in dotted lines at bottom.)

The feed-water is made to enter at the pipe G and circulate up and down over the ends of the partition-Walls around to the dischargepipe H, entering the boiler at the check-valve J, located at the common point for such valves.

Instead of the water entering boiler at checkvalve J it may be made to enter at the front flue-sheet, as is shown by pipe K, Fig. 7, provided with a check-valve L, the Water entering the heater by the pipe M.

Should it be desired to shut the water off from passing through the heater, the valve N may be opened and valve 0 closed, (see Fig. 6,) and the water will then enter through the check-valve J to the boiler in the ordinary way.

The heater, being located as is shown, is heated on the outside by the hot gases from the flues and on the inside by the heat of the exhaust-steam, and by reason of the long distance of travel up and down around the nozzle the water gets heated to the desired temperature before entering the boiler, thus making a great saving of fuel. The nozzle is so constructed that the closure of the waterspaces at the bottom is made by the surface to which the nozzleis bolted. Thus on removing the nozzle access may be had to all its cavities to remove the scale.

IVhat I claim is The combination of an exhaust-nozzle located in the smoke-box, of a water-jacket extending entirely around the nozzle, and provided with a series of vertically-arranged partition-walls, open alternately at the top and bottom, one wall being solid throughout; with an entry-pipe on one side of the solid partition-wall and an exit-pipe on the other side, whereby the circulatingwater is made to travel vertically up and down around the nozzle, substantially as shown and described.

In witness whereof I have hereunto subscribed my name in the presence of two witnesses.

PETER ALSDROFF KIMBURG.
